Quick architecture
Trezor★Bridge acts as a local HTTP/IPC endpoint that proxies requests to the attached Trezor device. For many modern devices WebUSB reduces the need for a separate proxy, but trezord/trezord-go and the Bridge daemon still play a role for compatibility and developer sandboxing. The trezord repositories and official documentation detail the RPC endpoints and why a local proxy is sometimes required. :contentReference[oaicite:12]{index=12}
Common developer flows
1. Use Trezor Suite (for end-user flows).
2. For web apps that cannot access WebUSB, use Bridge as the intermediary.
3. For developer automation, use the trezord API directly or script against the CLI utilities.
Example: curl-style test (concept)
// pseudo-request to local bridge
curl --request POST http://127.0.0.1:21325/connector \
--header "Content-Type: application/json" \
--data '{"method":"GetPublicKey","params":{"path":"m/44'/0'/0'","coin":"Bitcoin"}}'
Debugging tips
- Ensure Bridge/trezord process is running.
- Check OS-level permissions (macOS & USB access dialogs; Windows driver prompts).
- Confirm device firmware matches supported versions.
- For platform-specific issues consult the official deprecation and migration notes. :contentReference[oaicite:13]{index=13}

Security considerations for integrations
Keep integration surface minimal: never send private seeds to any process, restrict access to the local bridge only to the same user account, and prefer signed releases from Trezor when packaging Bridge binaries. For production services, treat the hardware wallet like a specialized HSM (hardware security module) with crisp separation of duties.
Roadmap & deprecation notes
Trezor has issued guidance about transitioning away from a standalone Bridge in favor of integrated Trezor Suite flows in some contexts. Follow the official guides for recommendations about uninstalling standalone Bridge and moving to supported Suite integration. :contentReference[oaicite:14]{index=14}
